You cannot back up DB2 for z/OS with TSM.
TSM does not understand traditional z/OS filesystems.
z/OS backup tools do not understand Windows and UNIX filesystems.

How many TSM servers you need depends on the amount of data you will back up
per day.  One AIX server like a P550 is probably enough.  But  tell us how
many Gigabytes of data you need to back up per day, and we can give a better
answer.



Whether you need more than 1 TSM server
